However, AFAIK, this would not fit with the JBoss' specification, which says that JNDI-lookups for local IF's (in the same VM) result in a reference to the instance, not in a serialized copy. More accurately, local calls are still passed through a Proxy (which is what you obtain from JNDI) which will directly invoke based on reference. There are conditions, however, based upon the type of Exception thrown and the transactional context of the method you're invoking, where the EJB3 spec dictates that the instance must be discarded. In this case, you'll receive the Exception from Seam, the SFSB instance would be discarded, and then you'd invoke on the same Proxy referencing the discarded instance and receive the error message above. EJB3 Core Spec 14.3.1 Table 14. Maybe try losing the @In annotation and slimming things down to tackle this one problem at a time? If you can get past the Seam exception and make subsequent invocations on the proper SFSB (whose stub you store in the HttpSession), then that'll give us some indication we're on the right track.
